Meroni ,   et al. | February 23, 1993 |
An automatic device for positioning a mechanical yarn feeler against a yarn. An extendable arm is provided with a magnet at one end. The magnet is held in a pivotable base which pivots within a limited range on the arm. The magnet actively engages the feeler when the arm is extended and as the arm retracts to lower the feeler onto the yarn, the magnet rotates with respect to the arm. When the magnet rotation reaches its limit, the magnet disengages the feeler and the feeler becomes passively supported on the base. The feeler is then further lowered to rest against the yarn and the arm retracted out of engagement with the feeler.
